IMPRovl-:MENT IN PuMPs.

Specification forming part of Letters Patent No. 176,079, dated April11, 1876 application filed March 11, 1876. I

To all 'whom it may concewt:

Be it known that I, THOMAS K. SHEP4 HED, of Ottumwa, in the county ofWapello and State of Iowa, have invented certain new and usefulImprovements in Pumps; and l do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawing, and to the letters of reference marked thereon,which t'orm part of this specification.

The nature of my invention consists in the construction and arrangementot' a submerged pump, as will he hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the anneXed drawing, whichrepresents a Vertical section of niy pump.

A represents the pump-cylinder, open at the top, and provided at itslower end with an elbow, B, turning upward and joined to the pump-stockO. In the joint between this pnmp-stockand the elbow is inserted arubber valve-seat, a, upon which the glass ballvalve bis seated, saidball being allowed to play upward. ln the cylinder A is placed thepiston or plunger D, connected, by a rod, d,to a suitable lever orhandle at the top of the well for Operating the same. The plunger iseither perforated or open at the top, to allow the water to pass downthrough it, and at its lower end is formed the valve-seat and a cage, G,is attached to and depends from the plunger. In this cage is a rubberball-valve, h, to tit in and close the valve-seat at the downward strokeof the plunger. This pump is intended to rest on the bottom of the well,and be entirely submerged in the water. At the upward stroke of thepiston the valve h opens, allowing the water to pass down- Ward into thecylinder, and the weight of the water in the pump-stock O keeps theValve b closed. As the plunger goes down the valve h closes, and thewater is forced by the plunger through the elbow B, opening the valve b,and u p through and out of the pumpstock.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination of the cylinder A, elbow B, pnmpstock O, horizontalrnbber valve- `seat a, forming the joint-packing, and glass THOMAS K.4SHEPHERD.
